I have two Montana's, a 300 WSM and 338 Federal. I have been shooting the 300 quite a bit lately after tweaking on it and developing a load. I Floated the barrel, lapped in the lugs as only one was in contact, larger diameter front screw hole, etc. The barrel seems to hold more copper than my quality barrels after shooting. I know and agree that one should not have to tweak on a $1000 rifle, but I think it may be needed on these Kimbers. Mine is shooting right at 1/2" now at 100 yds. I am satisfied with the rifle overall and may buy a 308 next. And I agree with the above post when shooting off bags, I place my left hand in front of the scope and hold the barrel firmly, butt firmly in shoulder, and a firm grip with the right hand. I also tightened the guard screws real tight. Good luck tuning your Montana into shape.
